Abstract
Experiments were conducted as pot experiment during the 2019 of kharif seasons to investigate the inducing drought tolerance to rice variety CAU-1 by seed priming at poly house of College of Agriculture, Central Agricultural University, Imphal. The experiment was laid out in Completely Randomized Design (CRD) with four replications and six treatments. Seeds were soaked in 1 % and 2 % solutions of KNO3, CaCl2, 40 ppm and 50 ppm of salicylic acid for 12 hours. Rice plants were induced to drought by applying Mannitol solution (100 mM) at 10 days after emergence (DAE) of seedlings. The results revealed that seeds primed with 2 % KNO3 showed the lowest days to 50 % germination and mean emergence time, maximum number of seedling leave, seedling height, root length, and root biomass. The treatment of 2% KNO3 followed by 50 ppm salicylic acid were found to be superior among other treatments in most of the parameters.
